Composite wing aircraft with dihedral angle

Abstract

The invention relates to a composite wing aircraft with a dihedral angle, which belongs to the technical field of aircrafts. The composite wing aircraft with the dihedral angle comprises an aircraft body, a left composite wing, a right composite wing, a tail wing and a landing gear. An operation system and airbore equipment are mounted in the aircraft body. The left composite wing and the right composite wing have same structures and are symmetrically mounted on the left side and the right side of the aircraft body. The tail wing comprises a horizontal tail wing and a vertical tail wing. The landing gear uses a wheel type structure or a skid and wheel combined structure. A dihedral wing exerts an effect of stabilizingthe aircraft. The left composite wing comprises a wing axle, a front wing sheet, a rear outer wing sheet, a rear inner wing sheet, a dihedral wing sheet, a rotor wing and an engine. The rear outer wing sheet and the rear inner wing sheet both can rotate and swing around the wing axle. The rotating plane of the rotor wing is in a horizontal position. During the rotation of the rotor wing, flow fields of the upper and lower surfaces of the wing sheets can be improved to increase downwash airflow and delay airflow separations on the upper surfaces of the wing sheets. The composite wing aircraft with the dihedral angle, provided by the invention, has the advantages of safety, high efficiency and high mobility.

Description

technical field [0001] The invention relates to an aircraft with dihedral composite wings, which belongs to the technical field of aircraft, and in particular relates to an aircraft with composite wings. Background technique [0002] Traditional aircraft need a runway to take off and land, and cannot take off and land vertically. Traditional helicopters have high energy consumption, low efficiency, and low safety and stability. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned deficiency of traditional airplane and helicopter, invent a kind of convenient short-distance take-off and landing and vertical take-off and landing efficient, safe and stable band dihedral composite wing aircraft. [0004] An aircraft with dihedral composite wings comprises a fuselage, a left composite wing, a right composite wing, an empennage and a landing gear. The fuselage is equipped with a control system and airborne equipment. The le...
